Define catastrophic global warming. What level of warming would, based on peer reviewed literature, be catastrophic for the human race?
Sea level rise is out, we just agreed on that.
Drought, storms, hurricanes, rains, flooding all show no statistical change in frequency or severity from the past. So we can throw those out too.
None of those things are out, and we most certainly didn't agree on that.
Feel free to read the IPCC's report on the likely effects of warming over the coming decades.
